A popular Australian magazine has claimed that Prince Charles and Camilla are filing for divorce after almost 15 years of marriage.

New Idea magazine says that a "royal insider" has spoken of the struggles within the royal couple's relationship.

The Prince of Wales, 70, has reportedly been consulting with his divorce lawyer, Fiona Shackleton - a leading figure in the field who represented Charles during his divorce with Princess Diana in 1996.

The insider also told to the magazine that Charles had "already signed the papers."
